How clean is the air where you are?
Our national air pollution map uses results collected by you from our Clean Air Kits.
Enter your postcode on the map to find out how clean the air is where you are. Each point on the map marks where an individual, community or school has put up an air quality monitoring tube. Toggle the layers for extra detail.
What do the results mean?
The monitoring tubes on the map measured nitrogen dioxide (NO2).
The European Union has set a legal average annual limit for NO2 at 40µg/m3 (micrograms per cubic metre). Most areas of the UK are currently failing to meet legal limits set by the EU. And even at low levels, short term and long term exposure to NO2 can have significant negative health effects.
Weather has a large effect on levels of air pollution, so the results displayed on the map can only represent a snapshot of the air pollution for the place and time they were measured.
They can look very different from the annual mean – and are not directly comparable.
What do the map icons mean?
Higher air pollution snapshot means the tube was over the level at which the mean annual limit is set (40µg/m3)
Lower air pollution snapshot means the tube was under the level at which the mean annual limit is set (40µg/m3)
Local groups monitoring sites are the sites where our local groups have placed air monitoring tubes.
N.B. All the results from the diffusion tubes required calibration and adjusting alongside government figures. This is called a bias adjustment. We’ve spoken to experts in monitoring and have adjusted all the results for accuracy using a bias correction factor for the type of diffusion tube used.
